No problem, I will try to get some patches for review ready.

Exactly,

I would consider it as a two step problem. First add --all-units which
works as you specified in previous reply. Later on work on what you
suggested in here (on giving output somewhat more sensible C++ way),
following the very algo you mentioned.

I will first work on former first (--all-units) and then later move to C++ :)

Between thanks for your suggestions.
